Life saver, thank you so much. Just did it today and it seems worked. Next I will need to clean or exchange the copper “fin rolls” on top of the heating elements. They had build up on them. I cleaned them the best that I could.
Great video. Thank you! They wanted $299 for service call plus $800 for deep cleaning. Absolutely crazy. Took me about 2.5 hours from start to finish.
Wow thats steep, glad it helped!
Thank you so much for this in-depth video. The other videos we watched did not completely disassemble the unit. We are so thankful to take hot showers again.
Glad it helped!
Thank you! Just followed your steps and have hot water now. 30 minutes or so. You saved me a bunch of $$ and aggravation... Interestingly enough, it really didn't seem all that dirty to me.
It doesn't take much to cause you an issue, glad it helped!
Thank you for this video! My burner was full of dead flies.
Thank You! That's so helpful. I've been watching a lot of Rinnai troubleshooting videos and I'm concerned that nobody mentions whether or not they are working on a condensing type or not. As if we should know that by looking. cheers..
Thanks for this video, been dealing with a finicky code-11 for about 6 months, tried resetting it, cleaning flame rods, replacing flame rods... followed your instructions and she works like new again. Cheers.
Awesome. Glad it was helpful for you!
Fantastic addition to our island kitchen
Great video. Followed along and we are up and running again. Saved me a few hundred bucks. Thank you.
Glad it helped, I'll be doing some maintenance videos for rinnais soon, subscribe if you want to see them!
Thanks, did what you said in the video along with take apart each individual burner scraping out lint, bugs and dirt them blowing each one out with air. I also blew off the burner assembly. My rl94 is like new!!
Awesome! It's crazy what gets inside these things
Thank you for the video.. it helped me out..
Thank you Sir!, good Info. Saved me bucks.
Glad it helped! Subscribe if you want to see some more rinnai tips, I have another one coming soon
Smith HVAC, Your video was spot on but like most disassembly / assembly I do, I have two screws left over. They are longer the all the others. Can you tell me where they go for an RL94?
Some of the outer screws around the burner plate are longer than others. Hard to say where yours are from, if they are fine thread machine screws they are off of the gas assembly.
Awesome video.
Thanks very much - this video gave me the confidence to get into my Rinnai v65 and solve the problem myself. Having the camera so close to where you're working is an excellent setup - it was easy to see what was going on, and the occasional voice-over comments were exactly what I needed. I'm not sure if you're still responding to comments a year after the video, but for my setup, even though the heat is working again, there's now a fairly significant odor of natural gas whenever the tank is running (not just during initial startup). Could I have missed something putting it back together? Do I need to replace some gasket somewhere?
Around 2:50 he mentions there’s a gasket you should replace if it falls apart. Im not a technician at all though, but it might be your issue
@@whocantexplain Thanks for the reply. I went ahead and replaced the full rectangular gasket around the burner plate (which was pretty tightly compressed after 7 years), and that seems to have fixed it.
Hey, sorry I didn't get to your comment until now. Glad you got it sorted out!
Thank you for a great video, just a few question do I need to replace any of the gaskets? Also how can I check for gas leaks just want to make sure everything is back together properly. And once again thank you.
No as long as you didn't pull the flame sensor gasket out you're ok. I like the PT299 gas leak detector. It's cheap and it works great. amzn.to/48EhKYX
When removing the two bottom’s screws to get into the burner housing unit i dropped a screw and it fell into the vent motor. Can i still run it like that? If not how do i remove it?
I would try to remove the vent motor, you don't want to risk damaging anything.
Model number?? I have a 12yo RC98 looks similar. Never had a problem or code with it great unit. Was just browsing, saw your video, thanks.
This is an Rl75, they used the concentric vent kit and were very reliable. The spiders nests is the most common issue I see on them
So to be clear , you cleaned out the burner to solve the issue?
Burner and orifaces, there are other issues that can cause a code 11 but this one was plugged up.
I had a hard vibration from my R75LS. I carefully took the fan out, cleaned it (lots of debris) and put it back in. No vibration now, but I have a code 11. Any ideas please?
Did you clean the burner? If the fans dirty, the burners dirty.
It was working fine before cleaning fan, just a loud hum/vibration. Are you suggesting code will trigger after cleaning fan if I didn't clean burner? I mean, what your saying makes sense - there were quite a few wasps and moths in the fan.
@@stretched2 cleaning the fan could have dislodged and sent some other debris into the burners. It's definitely the next thing I would check!
So, I took my time and carefully cleaned the burner and cleaned the coils above it. Checked the fan again and sucked anything out of the air assembly to the fan. Put everything together and it still throws code 11. Any ideas? I only disconnected the burner solenoid when I took the fan out - that couldn't possibly be that sensitive, no?
@@stretched2 Do you have good spark? Possible the spark ignitor came disconnected? Go outside near the exhaust while the unit tries to fire, do you smell gas?
Hi so I’m still having the problem! Could I have missed something! It worked all the rest of the day I did this then in the morning it started doing it again so I took it all apart and re did it, it started working again all night then now I just woke up and it started doing it again
Could be a number of different issues, this is just a common one. Check your intake and exhaust outside, maybe pull your vent apart and check in the intake on top of the tank, make sure your flame sensor and spark ignitor are clean
So do you think the igniter could be bad? I took those out flame rod and electrode cleaned them it fired up but now it’s doing it again not sure what else vent is clean
@@estebanvillagomez1465 blow your line out. If you have a regulator on your meter run , regulator could be bad.
Where is the air intake filter on this unit? Everything I see keeps saying top right side and will slide out towards me, but I don't see anything that even remotely looks like that.
The Rl75 doesn't have a filter, just the newer models
Do we have shut off the gas?
Yes
I have two decently long size screws and I have no idea what they go to..
Are they the ones you need the long screwdriver for? Out of the bottom of the burner
@@SmitHVAC. not entirely sure tbh I’m not a professional I just thought id have a crack at it. Funny solution, the gas wasn’t on at my house. Found out when I went to go cook and had no gas lol. So now I have another problem, my water heater is in my garage and it smells like gas in there now. Did I possibly do something to cause a gas leak? What would cause the smell of gas from the water heater? I didn’t mess with the gas line at all
Yes if you have leftover screws and smell gas you may have caused a leak, it would be best to shut it down and call a professional
@@SmitHVAC. that’s what I was thinking, thanks!
@@SmitHVAC. update, I’m stubborn and wanted to fix it myself lolll. I found where the screw goes and now it doesn’t smell like gas. Also, the two longer screws I originally commented about were the bottom two for the gas plate? I guess is what it’s called. I placed two of the screws for that big plate at the top for it (the one that holds the gas solenoids). Once I figured out that they don’t belong there I replaced them with the two bigger screws that go there at the bottom and then I missed one of the smaller screws that hold that big plate in. I guess that causes a gas leak since I no longer smell gas
How to installation for a electric tankless hot water heater
Nobody installs electric tankless around here, gas is cheaper
What should I do if water leaks?
Depends where it's leaking from
@@SmitHVAC.it’s leaking inside
You'll need to figure out where, could be a gasket, a valve, or a pitted copper pipe. If you can't find where it's coming from you'll need to call a pro.
mine is the infinity 16 brand new and i got code 11.
Are you in the southern US? I've never seen one of them in Canada
@@SmitHVAC. No. Mauritius (Strangely, we are Asian/Africa/Europe). Anyway, mine is the Rinnai Infinity A1620WD (made in Japan). I played with the settings and now the code 11 is gone and everything is good for now.
Got stuck because the screw driver I went to go out and buy specifically for this is too short :(( loll
Square or Torx Type screws would work better
Have you stripped a lot of these? I've never had an issue
Mine is throwing a code 11 and it is brand new....
This will not likely be your issue. Is the gas line or regulator sized appropriately?
Same thing with mine and it’s brand new
these are junk. cold water every 3 months...
I guess this one was about 8 years overdue lol you are mistaken..
Ive had mine for going on 8 years in November! This the first I’ve had a problem I did this and so far so good thank you
Glad it was able to help you!
